Figure 2 is a rear view of the devices shown in Figure 1.Y y p Figure 3is a view in cross-section, taken on the line 3-3 of Figure 2, the partsbeing shown in normal, or writing, position.

Figure 4 is a view similar to that of Figure 3, the parts being inposition forv linefeed of the ledger-sheet relative to thestatement-sheet.-

'Figure 5 isa perspective view ofthe platen-frame and.` attachedparts,looking down from the left rear corner.

Figure 6 is Vdetail view, showing one of the brake-units and itsactuating carrier in i their relationto onefront and one rear feedendframesv 13Y and 14, which are connected roll. Y

The platen 10, of the usual cylindrical type, is carried by an axle 12,journaled in by cross-bars 15 and 16. Finger-wheels 17 i I; ried byangular brackets 20 which are jour naled at the ends of their uprightarms on j ,secured to`cross-bar 15. Mounted on shaft and 18 foractuating the platen 10 are pro- 1 vided on the ends vof vaxle 12, andsuitable line-spacing mechanism may be'provided. A shaft^19at the rearof the platen is car a shaft 21, supportedin the end frames `13 and 14,Vand whichhave forward extensions 19 are three-arm levers22, six innumber',

theforward arms 23 of which are pivoted at 24 to carriers or yoke-pieces25 at points intermediate oftheir ends. The yoke-pieces a 25'eXtendtransversely of the platenand be-x neath the same,and are providedat'their ends with shafts 26 and 27, carrying for,` ward feedsrollers 28and rear feed-rollers 29, respectively. In order tohold theffeedfvjrollers 28 andl 29 in eiective position,'rela Cil tive to the platen,helical springs 30 areconnected to cross-bar 15 at one end, and, by

meansof screws 30, to depending arms 31 of the three-arm levers 22. Itwill be seen that engagement ofthe screws 30? in the coilsv of thehelical springs BO--enables adjustment of the tension of the springs.Due to the use of the VVyoke-pieces 25 the pressure exerted by thesprings 30 will be j distributed between the forward and rearward setsof rollers.

` The shafts 26 and 27, opposite the central portion of the platen 10,are of greater length than the other shafts 26 and 27, and each ofthesecentral shafts 26 and 27 carries three rolls. Onlyy one'roll isVsupported on eachof the other shafts 26 andL 27.

ln order to control `the .positionrof theV three-arm levers Y22 andtheeffectiveness of the feed-rolls, shaft 21 is vprovided with aiinger-piece32 and with'arms33,fsecured fixedly thereon. Upon rotationVof shaft 21 Y by tlie iingerfpiece 32, the arms 33'will actuate the,correspendingY` upwardly, extending arms V34"`of 't`he three-armlevers22,

and cause withdrawalof the carriers oryokepieces 25, and consequently ofthe feed-roll'- ers 28 and 29 from effective position with respect tothe platen.;

It will be notedfthat the pivotsiati`24 arev situated to the rear of themiddle points of' yoke-pieces 25. AsY a;` consequence fof thisarrangement, the forwardv rolls 28 are withdrawn from, the platen beforethe'rear rolls 29; and, in order to insure withdrawal of said rearfeed-rolls,A resilient membersl 37 are` secured on cross-bar 15inposition to co-o-perate with the Yforward feed-roller shafts 26. As seenin Figureheach of the end members 37 serves to act as a stop-support forone end of a shaft 2 6, while each of the intermediate members 37 4actssim.-

ilarly on the ends of two of saidshalts` 'Y Y* and is forked to betteradapt it for that purpose. Obviously, each of tlievmembers 37 may bereplacedby two single members.

A paper-table 38 ispivoted at 39 to for wardly extending f arms 40 ofbell-.cranks pivoted on shaft 19v and having depending arms 41conneotedvby springsb` to the cross-bar 15. It willA beseentha't thesprings V 42 vtend to maintain theA paper-table in Vposition toco-operate with the platena AtV the rear,ctl1e paper-table restsfloatingly against certain ofthe parts 'supported on shaft21.

The depending arms 41 `are provided withV lugs 43 extendingv to the rearof the outside depending arms 31,` so vthat withdrawal of` the outerfeed-rollers willv effect withdrawal of the paper-table. Y, f Y Y i Uponmovement oflinger-piece82 toits extreme rearwardA position, thevfeed-rollers and the paper-table'will ,be` moved away form the platento permit'theV insertion'of the work, which, in this case, comprises astatement-sheet A; oppositeV the central roll-V ers, and a ledger-SheetB having its margins extending beyond the margins of the'state-VVment-sheet and in position tobe engaged by the outer rollers, acarbon-sheet@V being Vinterleaved between the Vwork-sheets. *Uponrelease of the linger-piece 32, the feed rollers and paper-table' willbe returned tortheir normal positions. f f: When the Vwork-sheets areplaced in vcooperative position with the platen 'as just de i scribed,the lines along which typewriting Aless diameter than the rolls prope`the statement-sheet against movement While the'ledger-sheet is tedhytheplaten.v

It will be noted that the direction of ap-v plicationV of the brakes isaway from the platen; that is to say, thepressure of the brakes isopposed to the pressure exerted by the springs 30. rlhe normal tensionof the springs is such that the feed-rolls would tendto turn and mightactually turn with the platen despite the brake action, unless thenormal pressure of the rolls on ,i the platen is relieved to soineextent; and,

Upon release or forward movement of the lever63 to normalposition, thepressure of VtheV brakes is relieved and the full effort of thosesprings 30 which have been relieved by the brake action becomes againeffective for line-feed of the statement-sheet with the ledger-sheet.
